What are you talking about? Do you have some sources explaining this? This just seems like the oft-used, "previously it was an anomaly, we are returning to normal" pseudo-science that gets dragged out about everything concerning climate change. "It's not getting hotter, we were just in a cold period".

The book Cadillac Desert makes that claim. When the water rights for the Colorado River were divided up, it was based on a quantity of water measured during a wetter year.

Yeah, but it's true. The period during which white settlers arrived in the American west was ridiculously wet. This presentation is a little irritating, but if you scroll about 80% of the way down you'll see the chart of tree ring data that shows tree growth was at a 1000-year exceptional peak during the 20th century. https://www.theguardian.com/us-news/ng-interactive/2021/jun/17/tree-rings-america-megadrought-visual https://www.theguardian.com/us-news/ng-interactive/2021/jun/...

  "The only reason this drought is lagging behind that 1500s drought is because it's so young," Williams said. Both of your links show how bad the current drought is. If the current drought miraculously reverses itself in the next several years, than what you're arguing could be true. However, it doesn't look like that will be happening - time will tell.

    Current drought is ridiculously bad, but is exacerbated by the ridiculously wet period that preceded it.

It's not exactly accurate because it doesn't account for water taken out for irrigation above this particular point, but it clearly shows the natural ebb and flow of the Colorado's volume.
